Abstract

In this work, the high energy hadron-hadron scattering is studied in the framework of holographic AdS/QCD models, using the Brower-Polchinski-Strassler-Tan Pomeron exchange kernel and gravitational form factors. We apply the configurational entropy techniques to estimate the slope of the total cross section for the total hadron-hadron cross sections at high energies. A good agreement is derived between our approach and the total cross section for combinations that include the pion-nucleon, nucleon-nucleon, and pion-pion, as well as for any high energy data with inclusion of data from the TOTEM collaboration at the LHC and approximated by the Pomeron exchange. In the case of pion-nucleon and pion-pion scattering, the agreement for the critical points to the differential configurational entropy can be reached within 1.1% even without the involvement of any extra parameters.
